Sorted List Array Question

On sorting an array i get : 1,10,2,3,4,5,6,7,8,9. What went wrong ?

My code was:

        NSArray *sortedArray = [optionKeys sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)];

where optionKeys were: 7,3,8,4,9,5,1,6,2,10

i had also tried CaseInsensitiveCompare: and got the same result.

Check out this answer. You want to do a numeric sort instead of a string sort.

String comparison will place 10 after 1. You'll need to use a number comparison function. This may help: How to let the sortedarrayusingselector using integer to sort instead of string
